heart rate monitor

US scientists on November 25 said they had measured the heart rate of an adult blue whale with a high-tech ECG recorder.

This new device can be used continuously. Users need to wear it on their arms, like a watch to make sure they fit into the artery.

Researchers at the University of Hiroshima in Japan have developed a new sensor system that detects the heart rate by amplifying the heart rate from the skin's back surface.

Scientists have found a way to charge non-wires for devices inside the human body.

To monitor cardiac arrhythmias, a monitor and electrodes should be attached to the person through the conductor and should not be attached more than 24 hours.

PoolmateHR is the world's first swimming meter to track laps, distance and heart rate measurements, giving stroke warning.

In the future, US soldiers will be able to use trousers, bras with body heat, heart rate, blood pressure and many other indicators of the body.
